The Difference

The increase in the line width of the 17O signal of CrO42- (ΔvCrO42- = 11�2 Hz) on adding acid is attributed to a much broader HCrO4- signal ΔvHCrO4). This broadening is shown to have acid-independent (Δv0 = 67�5 Hz) and acid-dependent [Δv1 = (1.0�0.1) × 108 Hz M-1] contributions. Direct T1 and T2 measurements give T1 ≈ 70 ms, T2 ≈ 40 ms for CrO42- with the difference being attributed to spin coupling (T2' = 90 ms). For HCrO4- T1 = 8�3 ms, and the acid- catalysed Δv1 contribution is attributed to rapid exchange of H,+ in H2CrO4 (k ≈ 1×109 s-1) showing that spin exchange effects are important for this ion.
